How to Unlock iPhone 3GS & Install Ultrasn0w 1.2.3 without Wi-Fi?

Hi, my iPhone has been successfully jailbroken on iOS 4.3.3 and the baseband of my jailbroken iPhone has been updated to 6.1.5.00 (iPad baseband). Now, I want to unlock it using Ultrasn0w but the problem is I don’t have access to any wireless network in my apartment. Is there a way to install Ultrasn0w into my iPhone using my computer? Thanks.

Hello Craig, yes, you can easily install Ultarsn0w 1.2.3 on your device using iPhone Explorer, Diskaid or iFunbox and Ultrasn0w 1.2.3 DEB file. To do that, of course you have to download Ultrasn0w 1.2.3 DEB file + MobileSubstrate package from this download link. On this tutorial, we were using iPhone Explorer, which can be downloaded from here. Once you have all the required tools and files, then you can now unlock your iPhone by referring on the instructions posted below:
